FASTENING DEVICE FOR, WINDOWS.

To all whom it may concern:

Be it known that 1, JAMES L. MALLORY, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fastening Devices for lVindows, of which the following is a specification.

My invention relates to a fastening device for windows and the invention has for its object to provide, as a protection against burglary, a simple, inexpensive, strong and easily operated sash-fastening device, by means of which the sashes of a window may be held against opening movement in any desired position, either closed or partially open, or which can be so arranged as to resist and prevent the moving of one or other of the sashes beyond a predetermined point.

A device having these general characteristics and purposes is shown and described in my Patent No. 913,833, granted March 2, 1909, several different structures embodying the same broad idea, being disclosed in said patent.

The special object of the present invention is to provide a device which shall be an improvement, in the several respects hereinafter set forth, over the structures shown in the patent. Furthermore, I desire herein to protect by patent, the feature shown in Fig. 5 of the drawings of that patent, which was not claimed specifically, nor specifically claimable, in said patent, namely, the provision of the device with a wedge, tooth or spur which is interposed, either initially or by the movement of one or other of the sashes between the lower sash and the window frame.

The invention has for further objects the other new and improved constructions and arrangements in relation to a window fastening device which will be described in the following specification and particularly set forth in the claims appended thereto.

The invention is illustrated in a preferred embodiment, and in one suggested modification, in the accompanying drawings, where- 1n Figure 1 is an elevation of a part of a window viewed from within the same, showing the application of my device to a window of ordinary construction; certain parts of the window and frame being in section.

taken at right angles to the planes of the window panes. Fig. 3 is a sectional plan view of the parts shown in the preceding figures. Fig. 4 is a view in perspective of the form of fastening device shown in Figs. 1, 2 and 3, and Fig. 5 is a perspective View of a modified form of device.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring to the drawings, 10 represents one of the jambs of a window frame of ordinary construction, 11 the stile of the upper sash, the pane of which is shown at 12; 13 the meeting rail of the upper sash, 14: the meeting rail of the lower sash, 15 the pane of such sash; 16 the stile of the lower sash; 17 the parting bead, and 18 and 19 the inner and outer beads, respectively, which hold the sashes in proper position. The stile 16 of the lower sash is shown as recessed at 20 for the knot 21 of the sash cord 22. It will be understood that this is an ordinary construction of window and forms no part of my invention. I

The fastening device of my invention might be applied to windows of different construction.

The device of my invention, as I prefer to construct it, consists of a transverse, or substantially transverse, member 23 and the upright member 2 1, which are rigid with respect to each other, being preferably parts of the same casting. The transverse member is formed at one extremity with the smooth, and preferably a trifle rounded, surface 25 which terminates in the sharp edge 26. This part is designed to engage the stile of the upper sash. The transverse member 23 is preferably formed with the outstanding edge 27, designed to engage the jamb 10 of the window frame. The upright member is preferably in the form of a double wedge, that is, it tapers from top to bottom and transversely, as shown. The wedge member is designed to extend, to a greater or less extent, according to the looseness of the parts, between the lower sash and the window frame. The tapering of this part, as above described, tends, through the pressure exerted by the lower sash, to keep the edge 27 in true engagement with the amb 10 and to compel an engagement between the end of the transverse member and the upper sash.

The device would operate, cess at least, without utilizing with some sucthe sash cord.

i in engagement with thoseparts.

I prefer, however, to provide for an engagement between the fastening device and the sash cord, whereby the sash cord helps to keep the sash and frame-engaging means i The device is, therefore, formed with a channel for the cord, which in the form shown in the first four figures, is a slot 28 which is open in front so that place without taking the window apart; and in the form of device shown in Fig. 5 is a perforation 29, this modified device being intended for use when the window is equipped with my fastener when first built. This channel for the cord is so arranged as to force the cord out of its normal vertical alinement, with the result that the pressure exerted by the cord on the fastener tends to keep the engaging edges in close engagement with the wood against which they bear. This arrangement likewise permits the device to be placed and held at any desired position above the lower sash, so that the fastener may be brought into action only after one or other of the sashes has been opened to a certain extent.

It will be seen that the transverse member 23 is tilted upwardly a trifle. This brings the edge 26, which is preferably a sharp edge, against the stile ll of the upper sash in the initial position of the device, that is, the position it takes before an attempt is made to force the sash. lVith the device in this position, if an effort be made, either to pull down the upper sash or to raise the lower sash, the action resulting from the engagement between the lower sash and the wedge-shaped part 24, and the action between the sash cord and the device, or of both of these sets of instrumentalities when both are employed, will cause the device to be rocked with respect to the upper sash and jammed between the same and the lower part and frame; the engagement of the sharp edge 26 arresting the tendency of the 'end of the transverse member 23 to slip on the sash, the actual locking engagement between the device and the sash taking place, however, upon the smooth surface 25, so that the forced engagement between the device and the sash will not injure the woodwork of the sash or its finish. At most, the end of the fastening device will make only a slight indentation in the stile which scarcely is perceptible.

As the device, when placed on the window, simply rests lightly against the sash, it has no tendency to scratch or otherwise injure the woodwork of the sash or its finish. It will be seen that if the engagement between the wedge 24 and the lower sash and the window frame is not suflicient to hold the surface 25 in stopping engagement with the upper sash, the continued movement of the sash which is being forced the device may be put in' will cause a tilting of the device so that the lowerinner corner of the wedge is brought against the bead 18, so that the device is jammed between the upper sash and the window frame. Likewise, if the space between the lower sash and the window frame is so large as to allow the lower sash to slide up over the wedge, it will come into engage- 'ment with the flange which I will, designate by the numeral 30, forming in part the channel for the cord, and thus tilt the device to its locking position.

The dotted line position in Fig. 2 shows the position of the device when an attempt is made to force the sash.

The device may be thrown simply turning the indicated by Fig. 3.

When it is desired to fasten the sashes in their closed positions, the wedge-shaped part 24 will be initially thrust between the lower sash and the window frame. l Vhen it is desirable that the window should be free to open to a certain extent, without disengaging the device, it may be placed above the meeting rail of the lower sash, in which case either sash may be freely opened until the engagement takes place between the lower sash and the wedge-shaped member, in which event the sashes will be locked together and against the window frame in the manner above set forth. The sash cord will hold the device in any desired position. It will thus be possible to set the device so that the window may be open for ventilation but can not be opened wide enough to permit the entrance of a mans body.

I do not limit myself to the exact devices, constructions and arrangements shown and described, as modifications might be devised which would come within the scope of my invention. I have combined, in the device shown, several different instrumentalities, the cumulative effect of which, when used in combination, is to provide an absolutely perfect safeguard against the unwarranted opening of the window. For example, I have shown a form of device which engages the two sashes and prevents either one from being given an independent opening movement and which also, by means of the edge 27 provides for an engagement with the window frame. This latter provision is, in a sense, auxiliary and might be dispensed with, but, of course, with some sacrifice of security. Likewise, I provide for holding the engaging parts of the device against the sash and frame by means of the wedgeshaped part 24: and also through the tension of the cord. It is advisable, though not necessary, to employ both of these instrumentalities. The device, provided with the wedge, might be used on windows not provided with a cord. I have referred to out of action by same on the cord, as the dotted line position in the means for sustaining the lower sash as a cord, but it will be obvious that I intend thereby to include a chain or other means used in substitution of the usual cord.
